I am a Master of Mathematics (Computer Science) student at the University of Waterloo where I am supervised by Dr. Edith Law. I earned my Bachelor of Science (Honors) at The University of Western Ontario with an Honors Specialization in Computer Science and a Major in Microbiology and Immunology.

In general, my research interests include:

  • Interactive Machine Learning
  • Distributed Systems
  • Big Data Analytics
  • Health Informatics
  • Human computation

I am specifically motivated by time-series related problems in the medical and cybersecurity domains.
